The cross section is substantially L-shaped, and an occupant M hangs an elbow m1 on the top panel 15b.

  The base material 25 of the upper surface panel 15b has a plurality of second slits 25a as panel weakened portions that are vertically formed in a row in the vehicle longitudinal direction in the middle of the upper surface panel 15b in the vehicle longitudinal direction.

  The top panel 15b can be shortened and deformed in the vehicle width direction starting from the second slit 25a by breaking the second slit 25a of the base material 25 with the impact load F2 in the vehicle width direction acting at the time of a vehicle side collision. That is, it is shortened and deformed into a mountain fold so that the approximate center in the vehicle width direction is pushed upward, thereby absorbing the impact load F2 and reducing damage to the occupant M (see FIG. 7). . Such a second slit 25 a is not provided in the second lid member 17.

  As shown in FIGS. 4 to 6, a plurality of bosses 31 having screw screw holes 31 a are opened at the lower end portion of the base material 25 of the side panel 15 a corresponding to the screw insertion holes 21 c of the support piece 21. The part 19 is projected inward and horizontally in one piece, and below the boss 31, a temporarily fixing claw 33 is integrally projected downward corresponding to the engagement hole 7 e. An opening 33a is formed at the base end of the claw 33 so that the claw 33 is easily bent when engaged with the engagement hole 7e.

  Then, the claw 33 is inserted and engaged with the engaging hole 7e from above to temporarily fix the first lid member 15 to the bulging portion 7, and the screw screw hole 31a of the boss 31 is inserted into the screw of the support piece 21. The lower end edge of the side panel 15a is attached to the upper edge end of the bulging wall 7a and the base end of the support piece 21 by screwing the tapping screw 35 into the screw threading hole 31a corresponding to the hole 21c. The part is fastened to the lower end of the side panel 15a.

  In this state, the protruding end 21a of the support piece 21 is located on the back surface side of the top panel 15b on the bulging wall 7a side with the second slit 25a as a boundary. Further, a gap S of, for example, 2 mm is formed between the back surface of the upper panel 15b and the protruding end 21a of the support piece 21 so that the upper panel 15b does not normally contact the protruding end 21a of the support piece 21 ( 5), when a load F1 such as an elbow load by the elbow m1 of the occupant M is applied to the upper panel 15b from above, the upper panel 15b is deformed downward and comes into contact with the protruding end 21a of the support piece 21. (See FIG. 8).

  Although not shown, in the second lid member 17, the projecting piece and the boss 31 are fastened by a tapping screw 35 using a screw insertion hole 21 c of a short projecting piece that replaces the support piece 21.

  A plurality of support legs 37 are integrally protruded downward corresponding to the fastening pieces 23 on the back surface (base material 25) of the upper panel 15b on the door trim main body 3 side with the second slit 25a as a boundary. . As shown in FIGS. 4 to 6, a plurality of bosses 39 having screw screw holes 39 a are provided at the lower end portions of the support legs 37 so as to face the screw insertion holes 23 a of the fastening pieces 23. It protrudes in one piece horizontally.

  Then, the screw screw hole 39a of the boss 39 is made to correspond to the screw insertion hole 23a of the fastening piece 23, and the tapping screw 41 is screwed into the screw screw hole 23a. Fastened from the width direction, the extended edge of the top panel 15 b is pressed against the door trim body 3 above the door trim body side opening edge 19 b of the opening 19.

  Accordingly, the first lid member 15 has the lower end edge of the side panel 15a supported by the receiving surface 7b of the bulging wall 7a, and the extended end edge of the upper surface panel 15b above the receiving surface 3a of the door trim main body 3. It is attached to the door trim main body 3 and covers the opening 19.

  Although not shown, in the second lid member 17, the support leg 37 is provided closer to the extending edge than the support leg 37 on the first lid member 15 side so as not to interfere with the various switches 11.

  As shown in FIG. 5, in the armrest 9 configured as described above, since the protruding end 21a of the support piece 21 has a gap S downward from the back surface of the top panel 15b as shown in FIG. It is possible to prevent the generation of abnormal noise without touching the protruding end 21a of 21.

  On the other hand, when the vehicle collides sideways, as shown in FIG. 7, the impact load F2 in the vehicle width direction acts on the door trim 1, and the door trim main body 3 is pushed with a strong force toward the inside of the vehicle. With the impact load F <b> 2, first, the first slit 23 b of the fastening piece 23 is broken, the fastening piece 23 is cut off from the door trim main body side opening edge 19 b of the opening 19, and the support leg 37 is cut off from the door trim main body 3. As a result, the attachment state of the extended edge side of the top panel 15b of the first lid member 15 and the door trim body 3 is released.

  Subsequently, the impact load F2 acts on the upper surface panel 15b of the first lid member 15, the upper surface panel 15b is pushed with a strong force toward the inside of the vehicle, and the second slit 25a of the upper surface panel 15b is broken. The center of the top panel 15b in the vehicle width direction is pushed upward starting from the second slit 25a and shortened into a mountain fold. This deformation action absorbs the impact of the vehicle side collision and reduces the damage to the occupant M. can do. At this time, since the extended edge side of the upper panel 15b is not connected to the door trim body 3 as described above, the shortening deformation of the upper panel 15b in the vehicle width direction is not hindered, and the impact absorption performance at the time of the vehicle side collision is improved. Can be increased.

  Further, since the support piece 21 is formed in a plate shape and the plate surface 21b is directed in the vehicle width direction, the support piece 21 does not interfere with the shortening deformation of the upper panel 15b in the vehicle width direction at the time of a vehicle side collision. The upper panel 15b can be sufficiently shortened and deformed to exhibit a high impact absorbing effect. Further, since the support piece 21 faces upward, it can sufficiently withstand the load F1 from above such as an elbow load.

  In FIG. 7, the support piece 21 is not deformed, but when the impact load F <b> 2 acts more strongly, the support piece 21 bends and absorbs the impact load F <b> 2, and further the engagement on the base end side of the support piece 21. The impact load F2 can be sufficiently absorbed by the support piece 21 by breaking the hole 7e.

  On the other hand, when a load F1 is applied to the upper panel 15b from above due to an elbow load or the like by the elbow m1 of the occupant M, the upper panel 15b is deformed downward and contacts the protruding end 21a of the support piece 21 as shown in FIG. Then, it is supported by the support piece 21 and is not further deformed. At this time, the cushion material 29 of the top panel 15b is pressed against the skin 27 and compressed, and the load F1 from above can be absorbed by the cushion material 29. Therefore, even when a large load F1 such as an elbow load acts on the top panel 15b, the top panel 15b is supported by the support piece 21 and can withstand a large load F1 from above.

  Further, since the base end portion of the support piece 21 is fastened to the lower end portion of the side panel 15a by the boss 31 and the tapping screw 35, the load F1 from above such as the elbow load by the elbow m1 of the occupant M causes the upper panel 15b to Thus, even if it acts on the support piece 21 greatly, the clearance S between the back surface of the upper panel 15b and the protruding end 21a of the support piece 21 is ensured with high accuracy so that the support piece 21 does not tilt in the vehicle width direction. The support posture of 15b can be stabilized and the upper surface panel 15b can be supported appropriately.

  Further, the rear surface of the upper panel 15b on the side of the door trim main body 3 is connected to the door trim main body 3 via the support leg 37, the boss 39, the tapping screw 41 and the fastening piece 23 with the second slit 25a in the middle of the upper panel 15b in the vehicle width direction as a boundary. Since the protruding end 21a of the support piece 21 projecting on the bulging wall 7a is disposed close to the back surface of the top panel 15b on the bulging wall 7a side, the load F1 acting from above such as an elbow load is supported. The top panel 15b can be stably and firmly supported by the support leg 37 and the support piece 21 in a well-balanced manner in the vehicle width direction.

  In the above-described embodiment, the plurality of second slits 25a formed in the base member 25 in the vertical direction in a row in the vehicle front-rear direction in the middle of the vehicle width as the panel weakened portion of the upper panel 15b. Although the case where it is a slit row was illustrated, it is not restricted to this, and a plurality of slit rows may be provided in the vehicle width direction. Moreover, it may be a groove instead of the slit, and in the case of the groove, it may be continuous in the vehicle front-rear direction. Furthermore, it is good also as a panel weak part by forming the base material 25 whole thinly.

  Further, in the above embodiment, the protruding end 21a of the support piece 21 is inclined obliquely upward to receive the load F1 from above such as an elbow load on the inclined surface. You may make it receive the load F1.

  The present invention is useful for a vehicle door trim having an armrest.
